hypothesis

a prediction derived from theoretical analysis that is couched in a form precise enough to be subjected to testing against empirical data. In economics, hypotheses are generated by a process of logical deduction from sets of initial assumptions about the behaviour of consumers, producers, etc., and are generally tested by collecting economic data and using statistical techniques to analyse them. This testing can lead to modification of the economic theory in the light of the new economic data or to abandonment of that theory in favour of an alternative theory that better explains the facts. See HYPOTHESIS TESTING.

To do this, we develop classical hypothesis test statistics that can detect systemic risk.
Building of statistical models, like hypothesis tests for the difference between two population means, are used to verify or otherwise disprove the presence of relationships between interacting variables.
The economist will reject this null hypothesis if and only if the hypothesis test yields both an estimate of the change in the stock's value that is non-zero, and an error rate of the test that convinces the economist that sampling error has not caused the nonzero estimate of the change in the stock's value.

For binary outcomes, the standard procedures used to estimate overall odds ratios in the presence of strata were introduced by Cochran (1954), who first proposed a hypothesis test for the difference in proportions across strata.
